BLOWER FOR TH RES HlNG-MACHINES.

SPECIFICATION forming part of Letters ]?atent No. 645,311, dated March13, 1900. Application filed May 26, 1899. fierial No. 718,400. (Nomodel.)

To aZZ whom, it incl/y concern:

Be it known that I, JOHN D. DILLER, of Pandora, in the county of Putnam,State of Ohio, have invented certain new and useful Improvements inBlowers or Blowing-Machines for Threshing-Machines, Clover-Hullers,Huskers, Shredders, or the Like, of which the following is a'completespecification, reference being had to the accompanying drawings.

The object of my invention is to produce improvements in blowers of thekind described,- whereby they may be operated with comparatively-smallexpenditure of power, without breaking or crushing the straw, andWithout choking of the straw within the blower. Moreover, I provide mymachine with means for readily regulating its mechanism, and therebyadapting it with facility 7 to the work which it has to perform.

In the accompanying drawings, Figure I is a vertical section of myblower attached to or incorporated with a portion of a threshingmachine,also shown in vertical section. Fig. II is a perspective view of theexterior of my blower detached. Fig. III is a View of the blowerdetached, similar to Fig. 1, showing the riddlefdoor open and thefan-drum adjusted to the open position.

Referring to the numerals on the drawings, 1 indicates the tail-board,and 2 the shakerbar, between which is defined a chaff-chute 3,

a strawchute 4 being defined above the shaker-bar 2.

The above-described parts are specified in order to indicate therelations of my blower to a machine; but the remaining portions of themachine shown in Fig. I, being entirely non-essential and constitutingnot even a preferred form of the wide variety of machines to which myblower is applicable, do not require further description or detailillustration and are only exhibited incidentally in a partial andfragmentary manner.

Referring now to that portion which constitutes my invention, 5indicates a framepiece which may form a part of or be entirelyindependent of the machine to which a particular blower is applied. Theframepiece 5 is provided with an aperture 6 of sufiicient dimensions toinclude both of the chutes 3 and 4, or so much thereof as it may benecessary to include, the chutes being separated by the shaker-bar 2,which preferably works between the side walls of the aperture 6. To theouter face of the frame 5 is secured a hood 8-, having converging sidesthat preferably terminate in a throat 9, preferably constricted, as byinner converging walls 10. (See particularly Fig. 11.)

Preferably below the plane of the tail-board 1, as uponbearing-supporting studs 11, is revolubly mounted a shaft 12, carryingblades and constituting a rotary fan 13. The shaft is provided upon oneend with means for applying driving power to it-as, for example, apulley 14. (See Fig. II.) Above the fan 13 and secured to theoscillatory bar 2 I provide a series of independently-movable plates 15,their degree of downward movement being limited to a slanting position,substantially as shown in Figs. I and III of the drawings. These platesare preferably provided with covered apertures 16. They may be made asby striking up from the metal of which the plates are preferablycomposed a series of triangular lips 17, which being retained in theplates constitute coverings, as specified, for the respective apertures16. The plates 15 preferably terminate at their lower extremities beyondthe periphery of rotation of the fan 13 and, communicating with thestraw-chute at, discharge the straw clear of the fan and in proximity tothe throat 9 of the blower.

Through the movement of the plates 15 imparted bythe movement of the bar2, as well as through the currents of air forced through the apertures16, the straw is caused to pass freely from the chute 4 over the plates15 easily and without choking. The straw dropping clear of the fan 13 isnot broken, but is passed in good condition through the throat 9. The

a depending flange or lap 21, to cover which.

the shell maybe adjusted, as shown in Fig.

I, or from which it may be separated, as shown in Fig. III. By the meanslast specified the amount of airsupplied to the fan and the manner ofadmitting the air thereto may be regulated to a nicety.

The elements above described, comprising the hood 8, fan 13, and plates15, assembled substantially as described, constitute onecompletely-practicable form of embodiment of machine. I prefer, however,in addition thereto, to provide a tail-board extension 22, adjustable,as by bolts 23, working in slots 24 in the sides of the hood 8, wherebya free opening between the forward face of the shell and the outer sideof the frame-piece 5 may be provided for the separation of screeningsfrom the chaff or straw and the discharge thereof after separation.Through the adjustability, however, of the extension 22 and shell 18 theopening between the shell and the frame-piece 5 may be entirely closed,so that the screenings may be blown ofi through the throat 9, anoperation which would be desirable, for instance, if the screenings werecomposed principally of cheat or other worthless material.

It was specified that the fan 13 is located preferably below the levelof the plane of the tail-board 1; but it is obvious that its axis mightbe located in a plane above that of the shaker-bar 2, in which positionthe drafts created by it would draw upon the chute 3, upon the apertures16, and more directly upon the straw-chute 4. I mention this as anobvions variation and also to indicate that the position of theriddle-door 25, which is shown in the drawings as forming a part of theupper wall of the hood 8, may be located in the lower part thereof. Theriddle-door is designed to gain access to the interior of the machine,particularly the riddles, which require to be changed from time to time.It is preferably located in the upper part of the hood, as illus-*trated, because in that position it can be opened without interruptingthe operation of the machine, but would have to be kept closed at suchtime if located in the lower part of the hood 8.

WhatI'claim is- 1. In an apparatus adapted to be connected with agrain-separating machine, the combination with a frame comprising ahood, of a fan, an oscillatory bar, and independently movable plates,projecting in a slanting direction above and beyond the fan,substantially as set forth.

2. An apparatus comprising the combination with a hooded frame, anoscillatory bar and plate, of a fan carried on the frame, a shell aboutthe fan, and a tail-board extension in proximity to theshell,'substantially as set forth. I

3. An apparatus comprising the combination with a hooded frame and aplate, of a fan carried on the frame, a shell about the fan, and anadjustable tail-board extension, substantially as set forth.

4. An apparatus comprising the combination with a hooded frame,oscillatory bar, and plate, of a fan carried on the frame, and ashell-adj ustable about the fan, independently of the frame,substantially as set forth.

5. An apparatus comprising the combination with a hooded frame,oscillatory bar, and plate, of a fan carried on the frame, anadjustalole shell about the fan, and an adjustable tail-board extension,substantially as set forth.

In testimony of all which I have hereunto subscribed my name.

JOHN D. DILLER.
